TAYLOR CARTER AND BOWEN HENRY, OF FRANKFURT, KENTUCKY.

RATCHET-WRENCH.

SPECIFICATION forming part of Letters Patent No. 657,512, datedSeptember 11, 1900. Application filed February 27, 1900. Serial No.6,745. (No model.)

To (LZZ whom it may concern:

Be it known that we, TAYLOR CARTER and BOWEN HENRY, citizens of theUnited States, residing at Frankfort, in the county of Franklin andState of Kentucky, have invented a new and useful Ratchet-Wrench, ofwhich the following is a-specification.

This invention relates to improvements in wrenches, and particularly tothat class known as ratchet-wrenches,

An objectof the invention is to produce a wrench of this character whichmaybe quickly and readily adjusted to be operated either right or left.

Another object is to provide a wrench which may be quickly adjusted tonuts of various sizes.

A further object is to construct a wrench which may be conveniently usedupon rods or pipes.

A still further object is to construct a wrench of a minimum number ofparts, thus simplifying the same and reducing the cost of production.

With the above objects in view the invention consists of a handle orstock having a head formed thereon, a disk rotatable insaid head andformed with a ratchet and a stationary jaw, an adjustable jaw carried bysaid pointed out in the claims, and illustrated by the accompanyingdrawings, in which Figure 1 is a perspective View of my invention. Fig.2 is a side elevation of the same. Fig. 3 is a longitudinal sectionalview. Fig. 4 is a transverse section taken on the line 4 4 of Fig. 2.Fig. 5 is a perspective view of the ratchet-disk.

Referring now more particularly to the accompanying drawings, Adesignates the handle or stock of the wrench, having formed integ rallytherewith the circular plate B,formed with a circular slot or opening,and O a similar plate detachably secured to said handle, said platesbeing removed from each other,

so as to leave a space therebetween, and constituting the head of thewrench receiving the ratchet-disk. This ratchet-disk is formed about itsperiphery with the ratchet-teeth D, which occupy the space between saidplates, and on each side of said ratchet-teeth with the flanges E, whichextend into the circular slots of theplates. Formed on said disk andextending laterally of the wrench is a stationary jaw F. Said disk isslotted, as illustrated at G, and formed on the sides of said slot withthe flanges or track H. Movable in said slot is an adjustable jaw I,having suitable grooves formed therein to receive said track upon whichit moves and formed with the threaded stem J, which projects from saiddisk and receives a suitable clamping-nut K and washer L. Thus thismovable jaw may be adjusted to and from the stationary jaw, so that thewrench may be made to accommodate-nuts of various sizes. The jaw Fstands at one end of the slot G, with its inner face even with the endwall of the slot, and the jaw I projects fromsome intermediate portionof the slot, so that there is always a hole or opening 7 through thedisk equal to the distance between the two j aws,thercby permitting ofthe wrench being used on pipes or bolts where it is necessary for themto project through the wrench.

Positioned in suitable recesses in the handle or stock are the dogs M,formed on their outer ends with oppositely-disposed ratchetfaces N, saidjaws being normally held in engagement with the ratchet of the disk bythe coil-springs O. A pin P is carried by each dog, the same extendinglaterally therefrom and movable in a slot Q, formed in said handle. Saidpins project through the slots of the handle, and pivoted upon theexterior of plate B by a screw passing intermediately therethrough is athumb-piece R, which is adapted when moved in one direction to disengageone of the dogs from the ratchet and hold the same therefrom and whenmoved in the opposite direction to effect a similar may be operatedeither right or left, astmay be desired. It will be noticed that theclamping-nut for the adjustable jaw and the thumb piece for shifting thedogs are both located on the same side of the wrench, where tlfiei maybe .o'rfire'fi'ieiitly "operzi'ted; The stockor handle is formed in itsend with the Wren ch portion S, adapted to engage nuts of 'variousSIZGS. o

Byt-forming on eof the plates of the heed intgi'iilly with the" stac 6ili'ii'i'dle and me" stationary jaw integrally with the ratchetdisk itwill be understood that the'ljiimlief of parts employed in the wrench isreduced and the construction thus simplified and a reduc-- tion effectedin the costlof production.- V

The wrench may be convenient y positioned upon a pipe or red bi'iri'siei'ti'ti i the Sfiijie" thereon, the pipe or rod passingthroughthe hei' i-sk" sl'dt 'fite mte l H Having thus escu )ed 0111-invemiemwnswe e aim as new, 51nd d'esii e t6 secure I)?
